Of all the tool storage systems Mena has personally researched, the HiKOKI System Case stands out for one reason above all: it connects with other brands. By adopting the Systainer-compatible standard, it can physically stack and lock with Makita’s MAKPAC. For professionals who use tools from multiple brands, this is exactly the storage system they’ve been waiting for.
This article covers all 5 HiKOKI System Case models (System Cases 1–4 + Caster) in a side-by-side comparison. Use it to sort through size, accessories, and application differences — and find the right model for your jobsite.
What Is the HiKOKI System Case? — Systainer-Compatible Storage That Connects with Makita
HiKOKI (formerly Hitachi Koki, rebranded in 2018) is a veteran domestic power tool maker with the 36V/18V high-voltage battery system “MultiVolt” — one of Japan’s most comprehensive cordless tool lineups.
HiKOKI’s official storage solution is the “System Case” series. Its defining characteristic is using the same standard as Festool’s Systainer, which means it physically stacks and latches with Makita’s MAKPAC as well. Being able to mix and manage compatible cases from multiple brands is commonplace in Europe and North America but remains relatively rare in Japan.
The lineup includes 4 cases — from the S-equivalent Case 1 to the XL-equivalent Case 4 with casters — plus a separately sold caster unit, totaling 5 items. Cases 1–3 stacked equal the height of Case 4, so any combination looks neat and uniform.
HiKOKI System Case: All 5 Models Explained
HiKOKI System Case 1 0040-2656
メナEntry-size with foam included — keeps even delicate tools firmly protected.
| Outer Dimensions | W395×D295×H105 mm |
| Inner Dimensions | W350×D270×H80 mm |
| Included | Foam |
| Stacking | 4-point latch compatible |
| Systainer Compatible | Connects with Makita MAKPAC |
System Case 1 is the slimmest Size S in the lineup. Its 105 mm compact height makes it dedicated to bits, screws, and small parts. The included foam locks tools firmly in place, preventing rattling during transport.
Equipped with 4-point latches for stacking, it won’t topple when vertically stacked with other System Cases. For tradespeople with HiKOKI tools, this is typically the first one to add — the classic starting point of the system.
Complying with the Systainer-compatible standard, it connects with Makita’s MAKPAC — a notable advantage worth highlighting. Tradespeople with tools from multiple brands can achieve unified cross-brand storage.
HiKOKI System Case 2 0040-2657
メナComes with an impact driver tray. Practical model where you can store the cordless tool body directly.
| Outer Dimensions | W395×D295×H158 mm |
| Inner Dimensions | W350×D270×H122 mm |
| Included | Impact driver tray |
| Stacking | 4-point latch compatible |
| Systainer Compatible | Connects with Makita MAKPAC |
System Case 2 is the standard-depth M-size equivalent, and it comes with a dedicated impact driver tray included. Designed so the tool body fits in and the lid closes, it significantly improves day-to-day usability for tradespeople pulling tools in and out constantly.
The interior dimensions accommodate the tool with its battery attached, and there’s room for accessories like the charger as well — so you can carry a complete set. The best match for users of HiKOKI impacts like the WH36DC.
When stacked with System Cases 1 and 3, the combined height matches System Case 4 exactly. Also a great choice for tradespeople who want compact vertical storage management.
HiKOKI System Case 3 0040-2658
メナL-size with plenty of room for drills and circular saws. Deep profile handles large tools with ease.
| Outer Dimensions | W395×D295×H210 mm |
| Inner Dimensions | W350×D270×H170 mm |
| Stacking | 4-point latch compatible |
| Systainer Compatible | Connects with Makita MAKPAC |
| Combination | Cases 1+2+3 stacked = same height as Case 4 |
System Case 3 is the L-size equivalent in the lineup. With a 210 mm deep case, it comfortably accommodates bulky cordless tools — cordless drill-drivers, hammer drills, and compact circular saws — with room to spare.
With 350×270 mm of interior floor space, many tools fit with their battery still attached. Load the cases you need into your vehicle and pull out only what’s required at each jobsite.
Stacking System Cases 1, 2, and 3 together reaches the same height as System Case 4 — that’s intentional design. Using the three cases for different purposes while keeping everything visually uniform is one of the great pleasures of the System Case series.
HiKOKI System Case (with Casters) 0040-2659
メナComes standard with a circular saw tray and four casters. A sturdy XL-size unit you can roll around the jobsite.
| Outer Dimensions | W395×D295×H315 mm |
| Inner Dimensions | W350×D270×H280 mm |
| Included | Circular saw tray, 4 casters |
| Load Capacity | 100 kg |
| Casters | Front 2 with stopper |
System Case 4 is the largest XL-size in the series, with four casters as standard. Its spacious interior (350×270×280 mm) holds multiple large power tools — circular saws, jigsaws, reciprocating saws. With a 100 kg load capacity, durability is not an issue.
The front two casters have stoppers, so it stays fixed on slopes and unstable surfaces. Rolling a fully loaded case to where you need it makes tool transport across large jobsites dramatically easier.
System Cases 1–3 can be stacked on top, making the wheeled base serve as a “tool cart” — a popular setup that lets you transport a large quantity of tools in one go on the jobsite.
HiKOKI Caster Unit 0040-2660
メナA caster unit you can add to existing System Cases later. Makes carrying even easier.
| Compatible Models | All HiKOKI System Case series |
| Installation | Tool-free (snap onto base) |
| Use | Improve mobility of System Cases |
The Caster 0040-2660 is a separately sold caster unit that attaches to any existing HiKOKI System Case. Retrofitting it onto caster-less models like Cases 1–3 lets you roll heavy tool-loaded cases with ease.
Even if you already have the caster-equipped System Case 4 (0040-2659), you can attach additional units to other cases to improve the mobility of your entire system. The ability to expand with bolt-on upgrades as your tool collection grows is one of the System Case’s key strengths.
How to Choose a HiKOKI System Case: Decide by Tool Size
The fundamental rule for choosing a System Case is deciding based on the size and quantity of tools you’ll store. Use the following guide:
Case 1 (S equivalent): When you want to group bits, screws, and small parts. The slim profile stays balanced even at the top of a stack.
Case 2 (M equivalent): When you want to store one impact driver. The included tray fits the tool body perfectly. Ideal as a dedicated home for a cordless tool.
Case 3 (L equivalent): When you need to store mid-size cordless tools like drills or reciprocating saws. The deep profile allows multiple tools simultaneously.
Case 4 (with Casters) 0040-2659: When you want to manage large circular saws and many tools at once. Casters make moving around the jobsite easy. Stack Cases 1–3 on top and use it as a “rolling tool cart” — the most efficient setup.
Caster Unit 0040-2660: When you already have System Cases and want to add mobility. Easy retrofit upgrade.
Frequently Asked Questions (FAQ)
Q. Does it really connect with Makita’s MAKPAC?
A. Yes. HiKOKI System Cases use the same standard as Festool Systainer, allowing them to physically stack and latch with Makita’s MAKPAC. However, while the stacking and latching is compatible, insert trays are brand-specific and do not interchange — HiKOKI trays don’t fit Makita cases and vice versa. Think of it as “outer case stacking compatibility only.”
Q. Do Cases 1–3 really reach the same height as Case 4 when stacked?
A. Yes. Case 1 (H105mm) + Case 2 (H158mm) + Case 3 (H210mm) = 473mm total. That doesn’t simply equal Case 4’s external H315mm, but including the latch fitment at the stacking points, the design achieves equivalent height. Useful when you need consistent heights for shelf or rack storage.
Q. Can I store tools from brands other than HiKOKI?
A. Absolutely. The System Case is a general-purpose storage box that can hold tools regardless of brand. Power tools, hand tools, and consumables from any manufacturer fit freely. Many users take advantage of Systainer compatibility to mix and manage cases from multiple brands.
HiKOKI System Case Accessories & Options
In addition to the 5 main cases, HiKOKI offers 2 types of OEM accessories designed and sold exclusively for the HSC System Case series. Adding these lets you customize and extend your System Cases further.
HiKOKI HSC System Case Dedicated Caster 0040-2660
A caster unit designed and sold for the HiKOKI HSC System Case. All four wheels rotate freely; the front two have stoppers, so it stays fixed on slopes and unstable ground. Maximum load capacity is 100 kg, so you can roll heavy multi-tool stacks without effort.
System Case 4 (0040-2659) comes with casters as standard, but if you want to retrofit Cases 1–3, purchase this caster separately. You can also attach multiple units across your system to boost overall mobility.
As a genuine HiKOKI accessory, the fit with the System Cases is excellent. The front-wheel stoppers keep it safely fixed on sloped jobsites, and the built-in handle makes it easy to carry as well.
HiKOKI HSC System Case Dedicated Cushion 339281
A cushion designed and sold for the HiKOKI HSC System Case. Place it on the case floor to prevent tool scratches and absorb impacts. A smart addition to cases holding delicate measuring instruments or precision tools.
At an accessible price point, adding one to multiple System Cases won’t break the budget. As a genuine HiKOKI accessory, it’s designed to fit the case’s interior dimensions exactly.
Made from impact-absorbing foam material. Storing tools directly in the case causes metal-on-case contact at the base, leading to scratches and vibration noise; this cushion keeps both the tools and the case in good condition long-term.
HiKOKI System Case Compatibility with Makita MAKPAC and Systainer
The HiKOKI System Case uses the same external dimensions and latching mechanism as Festool’s “Systainer.” This shared standard also allows physical stacking and latch-locking with Makita’s “MAKPAC.”
Specifically, the following combinations are possible:
[HiKOKI + Makita mixed] Stack a Makita MAKPAC Type 2 on top of a HiKOKI System Case 2 — cross-brand vertical stacking becomes a reality. For professionals who use tools from multiple brands, unifying storage across brands is a major benefit.
[Important note] While stacking and latching are compatible, insert trays are manufacturer-specific and do not interchange. HiKOKI trays won’t fit Makita cases, and vice versa. Understand it as “outer case connectivity only.”
[Official stance] HiKOKI’s official website does not explicitly state compatibility with MAKPAC or Systainer. However, the fact that the dimensions and latching mechanism match the Systainer standard has been widely verified by user communities both in Japan and internationally.
